But that which interested me most in reckoning up their divisions of time was the ascertainment of the average duration of life amongst them.

When all the boys, by practice in boxing, know pretty well whom they can in a friendly way lick, they are less tempted to more crucial experiments "without the gloves." But even the ascertainment of one's relative merits with the gloves hurts a good deal, and one may thank heaven that the fountain of youth (as described by Pontus de Tyarde) is not a common beverage.

Indeed, within the very small scale of incipient humanity corresponding to the stage of self-ascertainment (when signs were used and elements of language appeared), population and food supply were locked in the natural equation best reflected in the structural circularity of existence and survival.

This ascertainment is dictated by the pragmatic framework of the dynamic reality in which religion operates, and not by the memetic replication of its name.

Only after the agricultural phase, which corresponds to a level of efficiency of more food than immediately necessary, the element of competition shifts from survival to ascertainment.
